Comcast is one company. However, they act like they are still hundreds of little cable operators- all the various companies that they bought up through various M&A deals to become Comcast since they can't get their act together with regionalizing and standardizing their systems, channel lineups, internet offerings, etc. Comcast is a complete mess. They have let the legacy of many different systems slow them down massively with upgrades.
They are supposedly getting rid of Clear QAM nationwide, but then again, getting rid of analog took several years.
What's really scary is that they want to buy TWC, which has some of the same issues, although I'm not sure if they are as bad as Comcast's. Now add TWC and Comcast together, who have two totally different approaches to manage capacity, and you have an even worse situation than you have now. Comcast has done the right thing and rebuilt systems to 860mhz, except that they gave up partway through their rebuild effort, and never finished, and apparently have no plans to follow through with what they started doing, so some systems are upgraded and some aren't. I'm not sure about TWC on rebuilds, but they use SDV as a huge crutch in terms of capacity, and are now giving more capacity to HSI in order to offer Maxx.
Add in that Comcast is a Motorola provider, but has some Sci Atlanta systems, and TWC is Sci Atlanta provider, and you have an even bigger mess on your hands. You think either company is screwed up now? Wait until they try and operate as one company!
